I have a .pot file that came with my Wordpress theme. Now I want to add strings to it, that weren't there in the original theme. How do I do that?
Do I have to update the .pot file? but 1) How do I do that, and 2) How do I make sure that the strings that were translated won't get erased?
(I'm currently using Poedit and I can't see a feature to add a string.)

I think this question is not WordPress-specific enough to stay on this site, so maybe you should re-post it on Stack Overflow, or maybe Super User (since you also mention a program).

@Jan I edited the question so that it's more Wordpress oriented and not program specific
